How conservatives used trumped-up evidence to blame Democrats for Schiavo memo

From Media Matters:

Despite a lack of evidence, several media sources have repeated conservative speculation and accusations that Democrats secretly authored a "talking points" memo that described the Terri Schiavo case as a "great political issue" for Senate Republicans. These baseless accusations, apparently hatched on right-wing blogs and in conservative media such as The American Spectator, were given credibility by The Washington Post and CNN's Inside Politics. But as recent reports indicate, Sen. Mel Martinez (R-FL) has admitted publicly that one of his aides is the true author of the memo.
